[jira] Commented: (HBASE-2872) Investigate why regions in transition are updated to the same state multiple times

["Jonathan Gray (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-2872?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12891865#action_12891865 ] 

Jonathan Gray commented on HBASE-2872:
--------------------------------------

Over in HBASE-2697 I posted a review for a new zk assignment class.  It lays out much more explicitly what the valid transitions are and should help protect against this from happening down the road.

> This is related to HBASE-2866 Regions going permanently offline. The fix prevented multiple duplicate updates from going to ZK. But the master still tries to update these regions.
